Windshield , Garnish moulding and Dash rail ?

[warren va]

I have painted myself into a corner. Have tried for four hours today to install the three items using several different sequences with no success.
I installed the garnish mouldings first and could not get the dash rail or windshield hinge installed. Installed the dash rail then couldn't get the garnish mouldings in place. What am I missing here? I don't want to force them in and destroy my paint job. Will someone please tell me what I'm doing wrong.
Thanks
Warren
